Noise/Vibration Information

Measured values determined according to EN 50 144.

Typically the A-weighted noise levels of the machine are: Sound pressure level: 89 dB (A); sound power level: 102 dB (A).

Wear hearing protection!

The typically weighted acceleration is 5.0 m/s2.

The machine is intended for cutting, roughing and brushing metal and stone materials without using water. For cutting stone, a cutting guide is required.

For machines with electronic control: With approved sanding tools, the machine can be used for sanding and polishing.

Information on Structures

Slots in structural walls are subject to the Standard DIN 1053, Part 1 or country-specific regulations.

These regulations are to be observed under all circumstances. Before beginning work, consult the responsible structural engineer, architects or the construction supervisor.

For Your Safety

Working safely with this machine is possible only when the operating and safety information are read completely and the instructions contained therein are strictly followed. In addition, the

general safety notes in the enclosed booklet must be observed. Before using for the first time, ask for a practical demonstration.

Wear protective glasses and hearing protection.

Wear additional protection equipment for your safety, such as protective gloves, sturdy shoes, hard hat and apron.

The dust that is produced while working can be detrimental to health, inflammable or explosive. Suitable safety measures are required.

Examples: Some dusts are regarded as carcinogenic. Use suitable dust/chip extraction and wear a dust respirator.

Dust from light alloys can burn or explode. Always keep the workplace clean, as blends of materials are particularly dangerous.

If the mains cable is damaged or cut through while working, do not touch the cable but immediately pull the mains plug. Never use the machine with a damaged cable.

Connect machines that are used in the open via a residual current device (RCD) with an actuating current of 30 mA maximum. Do not operate the machine in rain or moisture.

When working with the machine, always hold it firmly with both hands and provide for a secure stance.

Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.

Always direct the cable to the rear away from the machine.

Always switch the machine off and wait until it has come to a standstill before placing it down.

For power outage or when the mains plug is pulled, unlock the On/Off switch immediately and turn it to the off position. This prevents uncontrolled restarting.

The machine must be used only for dry cutting/ grinding.

For all work with the machine, the auxiliary handle must be mounted.

Hold the power tool only by the insulated gripping surfaces, when performing an operation where the cutting tool may run into hidden wiring or its own cord.

Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

Use appropriate detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance.

Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property damage or may cause an electric shock.

For work with grinding or cutting discs, the protection guard 6 must be mounted. For work with the rubber sanding plate 13 or with the cup brush 16/disc brush/flap disc, the hand guard 12 (accessory) is to be mounted.

Use dust extraction when working with stone. The vacuum cleaner must be approved for masonry dust. When cutting stone, use the cutting guide.

Do not work with materials containing asbestos.

Use only grinding tools with a permissible speed at least as high as the no-load speed of the machine.

Check grinding tools before use. The grinding tool must be properly mounted and turn freely. Perform a test run for at least 30 seconds without load. Do not use damaged, out-of-round or vibrating grinding tools.

Protect the grinding tool from impact, shock and grease.

Apply the machine to the workpiece only when switched on.

Keep hands away from rotating grinding tools.

Pay attention to the direction of rotation. Always hold the machine so that sparks and grinding dust fly away from the body.

When grinding metal, flying sparks are produced. Take care that no persons are endangered. Due to danger of fire, no combustible materials should be located in the vicinity (spark flight zone).

Be careful when cutting grooves, e. g. in structural walls: See Information on Structures.

Blocking the cutting disc leads to jerking reaction forces on the machine. In this case switch off the machine immediately.

Observe the dimensions of the grinding discs.

The hole diameter must fit mounting flange 8 (M 14), 17 (M 10). Do not use any reducers or adapters.

Never use cutting discs for rough grinding. Do not exert any lateral pressure on the cutting discs.

Observe the manufacturer’s instructions for mounting and using grinding tools.

Caution! The grinding tool runs on after the machine is switched off.

Do not clamp the machine in a vice.

Never allow children to use the machine.

Bosch is only able to ensure perfect operation of the machine if the original accessories intended for it are used.

Mounting the

Protective Devices

Before any work on the machine itself, pull the mains plug.

Protection Guard

For work with grinding or cutting discs, the protection guard 6 must be mounted.

Place the protection guard 6 on the spindle collar. Adjust the position of the protection guard 6 to the requirements of the work process. Clamp with the screw 7.

The closed side of the protection guard 6 must always point to the operator.

Auxiliary Handle

For all work with the machine, the auxiliary handle must be mounted.

Screw the auxiliary handle 3 on the right or left of the machine head depending on the working method.

Hand Guard

For work with the rubber sanding plate 13 or with the cup brush 16/disc brush/flap disc, the hand guard 12 (accessory) is to be mounted. The hand guard 12 is fastened with the auxiliary handle 3.

Mounting the Grinding Tools

Before any work on the machine itself, pull the mains plug.

Use only grinding tools with a permissible speed at least as high as the no-load speed of the machine.

Grinding and cutting discs become very hot while working; do not touch until they have cooled.

Clean the grinder spindle and all parts to be mounted. For clamping and loosening the grinding tools, lock the grinder spindle 5 with the spindle lock button 4.

Actuate the spindle lock button 4 only when the grinder spindle is at a standstill!
